BLANK FDR USE IN MANUFACTURING DRINKING CUPS Original application filed July 15, 1920, Serial No. 396,342. Divided and this application filed September 14:, 1920. Serial No. 410,203.

To all whom it may concern. 1

Be it known that I, JosnrH V. \Vncn- BAUGH, a citizen of the United States, and a resident of New York, in the county of New York anl State of New York, have invented certain new and useful Improvements in Blanks for Use in Manufacturing Drinking Cups, of which the following is a specification.

The invention relates to a blank suitable for the manufacture of a sanitary drinking cup or container designed for temporary use, and constructed of flexible material such as a suitable grade of paper, the cup being intended, generally, to be discarded after having been used. The construction admits, also, of the cup being flattened by pressure to occupy a minin'ium space, and be suitable for packing and sale.

The invention has for its object a suitable blank as of paper from which a cup of this type may be folded in an extremely simple manner to afford a liquidtight container having a large capacity for the amount of material employed. The present application is a continuation in part of my copending application Serial No. 297,762, tiled May 17, 1919 and a division of my co-pending application Serial No. 396,342, filed July 15, 1920.

In the accompanying drawings, which illustrate the invention Figs. 1 to 4: are diagrammatic views illustrating he dilferent stages in the manufacture of a cup.

Fig. 5 is a perspective view of a completed cup.

Similar characters of reference designate corresponding parts thruout the several views.

leferring to the drawings, designates a blank composed, for example, of a suitable grade of paper of the required thickness and stiifness. This blank may be obtained in desired lengths as from a continuous strip 11, being cut therefrom along the line 12 to provide a parallelogram of substantially equal sides and generally in the form of a square. Qne of the corners, for example, the corner 13, of the blank is turned backwardly along a line 14 perpendicular to the diagonal 15 of the parallelogram, and the blank itswf is then turned overv about the said diagonal 15 as an axis or folded along same, .whereupon the full-lengthedges 16 and 17 are secured to each other in any suitable manner, for example by folding same inwardly. I prefer, in order to facilitate the turning and folding operations and final shaping of the cup, to crease or provide line impressions along the said diagonal 15 and line 14 perpendicular thereto as well as along the edges 16 and 17. Also additional radial line impressions 15 may be provided at either side of the diagonal. The edges may be secured to each other by means of a suitable adhesive, or may be folded over again, or preferably, are secured by means of a suitable binding strip or metal tape 18 which is bound over same, Fig. 4. This completes the cup which is thus securely scaled approximately from bottom to top along the lengthwise edges 16 and 17, in manner indicated, providing, also, a suitable mouthpiece 19. The latter is reenforced and stiifened by the backwardly turned corner 13, which serves, also, to hold the cup open as well as to round off that portion of the cup coming in contact with the mouth, thus obviating the sharp edges now found in the paper cups in general use. It may also be noted that by'depressing the corner 13, a shape is'given to the blank which will render the cup easy to drink out of, for by the elimination of this corner from the final contour a curved depression will be provided, from which the water will flow in a small stream instead of being distributed over a wide surface.

I claim 1. A blank for drinking cups substantially in the form of a square and having line impressions along two adjacent sides and a line impression at right angles to the diagonal between said sides.

2. A blank for drinking cups substantially in the form of a square and having line impressions along two adjacent sides, a line impression along the diagonal between said sides and a line impression at right angles to said diagonal.

3. A blank for drinking cups, two edges thereof being at right angles to each other and of equal length, two equal length edges respectively at right angles thereto and of lesser length than the first named edges, a connecting edge between the edges of lesser length and forming equal angles therewith;

and a triangular piece provided with impressions and extending from the connecting edge beneath the blank.

4. A blank for drinking cups having two edges substantially at right angles to each other and of substantially equallength, tWo other edges of substantially equal length at right angles to said first named edges and of lesser length; thang saidfirst named edges,; and a connecting edge between thejedges Ofi lesser length, adapted to provide a drinking lip hen said blank is formed.- into a cup With-said firstvnamed edges in contact.

5. A blank for drinking cups having two edges substantially at right angles to each other and o-fsubstantially-equal length, and

the blank having creases provided therein adjacent and substantially parallel to said edges. in; contact and folded over about the said parallel creases.
